CARTRIDGE.

SPECIFICATION forming part of Letters Patent No. 227,191, dated May 4,1880'.

' Application filed August 28, 1879.

To all whom it may concern:

Be it known that I, AUGUST TILLMES, of

- the city and county of Philadelphia, and State of Pennsylvania, haveinvented a new and useful Improvement .in Cartridge-Shells, of which thefollowing is a specification, reference being had to the accompanyingdrawings, in which Figures 1 and 4. are side elevations of thecartridge-shell embodying my invention. Fig. 2 is a longitudinal sectionof Fig. 1, showing the flange b turned in at a right angle to the wallof the shell. Fig. 5 is a longitudinal section of Fig. 4. Figs. 3 and 6are end views, respectively, of Figs. 2 and 4.

Similar letters of reference indicate corre sponding parts in theseveral figures.

My invention consists of a paper cartridge shell or case having the rearend of the case crimped, so as to embrace the edges of a flat innerdisk, and retained between said disk and an exterior re-enforce which isturned over and forms the flange of the cartridge.

It also consists of the exterior disk-shaped re-enforce, formed of metaland enveloping the offset of the shell, so as to strengthen the same forengagement of the cartridge-retractor.

, Referring to the drawings, A represents a shell, which is formed of atube of stout or strong paper crimped circumferentially near one end toform an offset, a, the extreme end or projecting portion b adjacent tothe offset being left somewhat flexible.

B represents the base, consisting of a disk whose diameter is slightlyless than the inner diameter of the offset a. This disk-shaped base issprung into the offset so as to snugly fit the same, and thus besecurely held in po sition atthe base of the shell.

The projecting end I) is folded over the base B, as in Fig. 2, thusproviding additional means of holding or sustaining the base.

0 represents a disk, which is termed an exterior disk-shaped re-enforce,and is placed against the folded end b of the shell and outer face ofthe base B, and secured thereto by gumming, if so desired.

Through the disk 0 and base B is passed the pin 01, which pierces thefulminate or capholder, which directs the tire of the cap to the tainedby the folded end b of the shell-resting against its outer face.

The re-enforoe G assists in holding the end I) in position against thebase B and provides additional strength for the base end of the shell.It is formed of metal, and has its circumference bent over by swaging,spinning, squeezing, or other means, so as to envelop the offset aexteriorly, whereby the latter, and consequently the base proper,isvastly strengthened, a strong metallic surface is presented forengagement of the cartridge-retractor, and the re-enforce retains itsposition.

Having thus described my invention, what I claim as new, and desire tosecure by Lettgrs Patent, is- K A paper cartridge shell or case havingthe rear end of the case crimped, so as to embrace the edges of the flatdisk B, and retained between said disk and the re-enforce O, which isturned over and forms the flange of the cartridge, all substantially asand for the purpose set forth.
